 Indicates *something that can be counted*, used both for comparisons and for multiplying uniques
 
 Allowed values:
+
 - `year`, `turns`
-- `Cities`, `Units`, `Air units` - these count your total number
+- `Cities`, `[cityFilter] Cities`
-- Unit name (counts your existing units)
+- `Units`, `[mapUnitFilter] Units`
-- `<unit type> units` (e.g. `Mounted units`) - counts your units by their type (this is not a filter, use the unitType verbatim)
+- `[buildingFilter] Buildings`
-- Building name (counts your existing buildings)
 - Stat name - gets the stat *reserve*, not the amount per turn (can be city stats or civilization stats, depending on where the unique is used)
